HYDROCARBON-OIL BURNER FOR FURNACES.

SPECIFICATION forming .part of Letters Patent No. 475,478, dated May 24, 1892.

Application filed November 16, 1891. Serial No. 412,096. (No model.)

To all whom it may concern.-

Be it known that I, JOHN WILSON, a citizen of the United States, residing at New York, in. the county and State of New York, have invented certain new and useful Improvements in Hydrocarbon-Oil Burners for Furnaces, of which the following is a specification, reference being had to the drawings accompanying and forming a part of the same.

This invention is a new and improved oilburner. I have devised the particular form of burner which forms the subject of my application for use in sewage and garbage disposal works and in connection with furnaces for incinerating the garbage; but its application to other furnaces and purposes will be apparent from the-nature of the invention and the objects which are accomplished by its use.

My object is to secure a cheap and effective device. I have utilized awell-known principle; but I have devised a special construction of the apparatus by which this principle is carried out, and I have introduced a new and a very effective feature in the means,whereby I supply to the ignited oil heated instead of cold air.

The improvements are illustrated in the accompanying drawings and specifically pointed out in the subjoined claims.

Figure l is a view in elevation of the apparatus complete. Fig. 2 is a plan View of a portion of the same.

A is a furnace for burning garbage or for any other suitable purpose and of any desired form of construction. It is presumed in the present case, however, that the combustion of the oil and other materials takes place therein mainly in the rear or in one portion more than in another, so that in one part of the furnace there will be a considerable volume of air or gas highly heated, but which has not been to any considerable degree deprived of its oxygen, so as to be incapable of supporting combustion. This would be the case in almost any furnace at the point where the air introduced by natural or forced draft had become heated by the combustion of the fuel taking place, but had not yielded all of its oxygen to maintain such combustion.

B is an ordinary fixture or coupling having a central chamber and four branch ports or outlets. To one of these latter is connected a pipe or tube 0, that leads into the furnace A. A steam-pipe D from a boiler E or from any other source from whence a constant supply of steam may be obtained is introduced through a plug in the port opposite to pipe C and extended through the said pipe to a point near its opening or end. A pipe F from an elevated reservoir G, of any suitable hydrocarbon liquid or which is connected with any other suitable supply of oil under pressure, connects with the steam-pipe D either within or without the fixture B or the pipe 0. This pipe F is provided with a cock f, by means of which the supply of oil can be regulated. Similar provision for regulating the admission of steam is also made byacock ein the steampipe.

To the two remaining ports of the fixture or coupling 13 are connected bent pipes H H, that lead into the furnace and open therein at the points where, as above described, the air and gases are highly heated, but not deprived of their combustion-supporting elements.

To operate this device, steam is admitted through the pipe D in regulated quantity. This steam takes up the oil delivered from the reservoir G and blows it out into the furnace in afinely-divided condition. The steam carrying the oil and issuing from the pipe D in the larger pipe 0 acts as an injector, creating a strong draft, which draws the heated air out of the furnace through the pipes H H, and forces it back, together with the steam and oil, into the furnace through the pipe 0. The

mixture of hot air, steam, and oil which is thus forced into the ignited gases within the furnace produces a very effective fire and an intense heat, which rapidly incinerates any solid combustible matter that may be introduced into it.

A number of th ese appliances, all connected with the same steam-boilerin the manner described, may be used with one furnace. This will depend upon the capacity of the furnace or the quantity of solid matter which it is desired to dispose of. I propose, also, to utilize, in connection with one or more of pipes O, the draft created by the injector action to ICO ing with the interior of the same in any suitable manner. In the pipe K or its branches are suitable dampers or valves to regulate the proportion of air or gas which is thus drawn in. Dampers N are also placed in the hotair pipes 11 to regulate the proportion of hot air that may pass through them.

What I understand to be new'aud patent able in my invention, and for which I desire to secure Letters Patent, is as follows:

1. The combination, with a furnace, of a four-way fixture or coupling 13, a pipe 0 from one port or branch of the same and opening into thefurnace, a steam-pipe entering the opposite port and extending into the pipe 0,

an oil-pipe froman elevated oil-reservoir conmeeting with the steam-pipe, and hot-air pipes leading from the interior of the furnace to the remaining ports or branches of the coupling, as herein set forth.

2. The combination, with a furnace, of the pipe 0, entering the same, a steam-pipe of smaller diameter extending into the pipe 0, an oil-supply pipe connected with the steampipe, hot-air pipes leading from the furnace J and communicating with the pipe 0 in the rear of the orifice of the steam-pipe therein,a jacket or casing surrounding the pipe 0 and communicating with the interior of the same in the rear of the orifice of the steam-pipe, said casing being connected or adapted for connection with a chamber containing nox' ions or disagreeable gases, and dampers in the hot-air pipes and those connecting the casing with the gaschamber, whereby the relative amounts of air or gas entering the furnace may be regulated, as set forth.
